An ice dam is a ridge of ice that forms at the edge of a roof and prevents melting snow (water) from draining off the roof. The water that backs up behind the dam can leak into a home and cause damage to walls, ceilings, insulation, and other areas.
Ice buildup on your roof can cause significant damage to your home. ... Ice dams are usually caused by poor ventilation in your attic. The warmer attic air melts the snow on your roof and the melting snow runs down your roof and under areas such as gutters before it is re-frozen by the colder outside air.
If you experience damage to the interior of your home, call your insurance company. Then call SERVPRO of E. Jackson/SE Ingham Counties. Once the ice has been removed, we can determine where there is moisture inside and get that dried.
